yond. the end oi. the conveyor and above the threshing cylinder B. The threshing cylinder B is located. between the sides of the box or housing A of the main separator housing and is of substantially the same length as the inside Width of the box A 1t mount ed on and rotates with the shaft B and is made up of the two end disks B which carry the cross slats B from which. project the teeth B. B is a stripper or heater wheel located within the main separator housing and slightly above and beyond the. cylinder and has for its function, rotating as it does in the same direction as the cylinder, to strip 0d the straw'which might otherwise become twisted around it.

G is an inclined grate section suspended .within the inain separator housing and of ending application No. 865,900, filed Oc- 16 1914-," and I. Wish this present ap-- bottom and upwardly and rearwardly in-' clinecl toward its upper edge immediately lit beneath the beater wheel 13. C C are side grate extensions parallel with the two ends of the cylinderand extending from. the ends of the grate C to the rear line or the housing or box A thus closing the aperture between the rear side-of the housing and the grate and confining the material which might otherwise be discharged more or less longitudinally from the cylinder. (1 C are curved grate sections located above'the up per edge of the grate C and extending; from the upper edges of the grates C and the upper edge of the grate C outwardly to the outer wall or the separator housing. These sections are COKlCQIl'tIlC with the heaterliand assist in closing the remainder oi. the

space between the housing it and ma l separator housing." (1 is a filler bloelr lo cated in the housing A and closing oft the space between that housing and the main housing above the eylindeir'. This tiller bloelr it will be noted-has on its inner side a vertical wall, on its bottom ourved wall concentric with the separatnig; cylinder, and v on its outer side a curved wall oonoentrie with the wheel B C is a concave grate seetion pivoted along the bottom line oi the grate C and having a slidable eonn U with a concave grateiseotion ooneaye grate tion U is supggortod at its inner and lower end by the bolt t3 curved slot C and at its upper forward end by the jaws C in engagement with an eccentric C, which eccentric is controlled by a handle C and ratchet C. These concaves, it will be noted, are just the length of the inside width of the housing A and completely fill it as it extends down as far as the lowest point of these concaves. The grates themselves are made up of grate sections as indicated c mposed of parallel bars tied together by the bolts C provided with spacing washers C and nuts C" and slidable in the slots C The concaves are also provided with teeth C which pass between the teeth B on the cylinder.

It is understood that the slidable connection between the concave and the grate is provided so that the distance between the concave 'and the cylinder may be varied at the will of the operator and so that a continuous connection is still obtained between the concave and the grate to prevent escape of material. It is evident also that this slidable connection permits expansion or contraction or bending or displacement of parts while the machine is in operation,

' without permitting the escape of the chaff to enter and they pass down between the cylinder and concaves. The rapidly moving feeder performs two functions. It spreads out the grain in the bundle, thus breaking up the continuity of the individual bundle, and also separates a great deal of the grain from the heads. This grain is knocked, rubbed and brushed out, passing through said concave, said grate having at either end extension grate walls parallel with the ends of the cylinder.

2. The combination with a separator, a cylinder and concave of a separating grate projecting upwardly and rearwardly from said concaves, said grate having at either end extension grate walls parallel with the ends of the cylinder, extensions projecting from the top of said walls to the adjacent sides pfthe separator.

3. A separator having a two-part concave, the parts arranged edge to edge, and means for adjusting said two parts to and from the cylinder, said two parts being separated by a sliding joint parallel withtheaxis of rotation of the cylinder.

4. In a separator having a cylinder, a two-part concave, the parts arranged edge pivoted on a fixed axis along its upper edge, means for bodily adjusting the other part to'and from the cylinder and a sliding connection between said parts.

In testimony whereof, I at'fix my signa-. ture in the presence of twowitnesses this twenty second day of January 1916.
